I've showed importing of Genesis 3 characters into Unity several times now. There is always one area that always looks like crap when imported. That is the eyes.

I took some time today to determine how to address this and this will be a short tutorial focusing just on that.

Here are my results

Using this texture:

Now there were three materials related to the eye it imported. I was messing with Bethany 7 as she is one of the figures I am reworking for our Wormhole Ventures game.

EyeMoisture (Material)
Bethany7_eyes_007 (material)
Cornea (Material)

So, eye moisture is intended for crying and tears and such. No texture exports for that and setting unity to transparent, fade, etc does not really help with this. Slapping the Eye texture here looks really ugly and that is what I showed in an earlier tutorial.

Instead I went into photoshop and created a white texture 64x64 and called it tears and set its opacity to 5%. I then used that in my EyeMoisture albedo texture. I went ahead and maxed out the smoothness. If you plan on doing a lot of crying and such you may want to tweak this and change the texture some.

This texture should work for you for Eyemoisture as long as you check Alpha is Transparency on the texture in Unity.
